You're on the gulf side of Florida, right? There were a lot of experiments in that area after the oil spill, like the one the USF students took part in here: NOAA - National Oceanic and Atmospheric Administration - Monitoring & Understanding Our Changing Planet
FADs can either be free drifting or anchored. Fishers construct drifting FADs to imitate natural drifting objects with some sort of float on the surface made of bamboo and other buoyant materials, but usually enhance the FAD with some sort of netting or rope hanging beneath them. Natural logs can also be enhanced and left it drift in order to attract tuna – those aggregations generally have the same characteristics as those found beneath manmade FADs. The key to a drifting FAD is the installation of an electronic buoy that reports its GPS position to the fishing vessel.
Good information.There is a chance that it was used by the French. This article describes them using bamboo rafts with netting and gps locators in the Atlantic ocean.
PLOS ONE: Large-Scale Examination of Spatio-Temporal Patterns of Drifting Fish Aggregating Devices (dFADs) from Tropical Tuna Fisheries of the Indian and Atlantic Oceans
We find that dFADs drift at sea on average for 39.5 days, with time at sea being shorter and distance travelled longer in the Indian than in the Atlantic Ocean. 9.9% of all trajectories end with a beaching event, suggesting that 1,500-2,000 may be lost onshore each year,
I saw it on Facebook and copied and pasted the photos here to help him identify it as a curiosity item. I will try to find it but it wont be easy because I cant remember the page i found it on.Can you tell me more about this photo off Islamorada. I'm interested in the who, when, and where.
